Detailed Solution

Using the “conduction tester” on an object it was found that the bulb begins to glow. The object is a conductor.
Materials that allow an electric current to pass through them are called conductors; the materials that do not allow the flow of current through them are called insulators. When two testers are touched to an object, the bulb will glow when current flows through it. As the bulb is glowing, the current is passing, so the object must be a conductor.
